You will find important safety

information in this supplement and

in the owner’s manual. This

information alerts you to potential

hazards that could hurt you or others.

Please read it carefully.

Your Civic GX operates and

performs like a gasoline-powered

Civic. However, there are a few

differences you should be aware of.

In addition to reading the Civic

Sedan owner’s manual, please read

this supplement carefully to

understand the operation and unique

features of your Civic GX.

Your Civic GX runs on compressed

natural gas (CNG), a highly

pressurized version of the same

clean-burning natural gas used in

many homes.

Introduction

Main Menu

This indicator comes on for a few

seconds when you turn the ignition

switch to the ON (II) position. If it

comes on at any other time, it

indicates one of the engine’s

emissions control systems may have

a problem. For complete information,

refer to the Civic Sedan owner’s

manual.

This indicator will also come on if

there is a problem in the fuel system.

If this happens, have the vehicle

checkedbyanauthorizedHonda

Civic GX dealer as soon as possible.

Drive moderately until the dealer has

inspected the problem. Avoid full-

throttle acceleration and driving at

high speed.

If you smell natural gas or hear a

hissing sound, except when refueling,

the fuel system may have a leak.

Follow the instructions under

on page

of this supplement.

If the outside temperature falls

below 25°F ( 4°C), the pressure of

the natural gas in the fuel tank may

go down. If this happens, the fuel

gauge will show less than the actual

amount of fuel remaining, and the

indicator may come on.

If this indicator starts blinking and

the fuel level reading goes down to

empty when the engine is running, it

indicates a problem in the fuel

system. Have the vehicle checked by

an authorized Honda Civic GX dealer

as soon as possible.

This indicator comes on for a few

seconds when you turn the ignition

switch to the ON (II) position. It also

comesonasareminderthatyou

must refuel soon. The approximate

driving distance remaining when this

indicator comes on is:

This gauge shows how much fuel

you have. The quantity of fuel

remaining in the tank is calculated

based on the pressure and

temperature of the natural gas in the

fuel tank.

The gauge may show slightly more

or less than the actual amount. The

outside temperature, fill method, and

ambient conditions may affect the

pressure and temperature of the

natural gas.

The lower ‘‘F’’ mark indicates a full

tank at a fill pressure of 3,000 psi.

The upper ‘‘F’’ mark indicates a full

tank at a fill pressure of 3,600 psi.

If you use a fuel that does not meet

these standards, you may feel a

decrease in engine power and your

vehicle’s emissions controls may be

damaged.

The main component of compressed

natural gas is methane, a highly

flammable, colorless gas. While it is

the same gas that is burned in

everyday home appliances such as

kitchen stoves and water heaters,

theCNGinyourvehicleisstored

under high pressure (maximum

3,600 psi/24,800 kPa).

Your Civic GX is designed to operate

on compressed natural gas (CNG).

The natural gas you use to refuel

must meet NFPA-52 and SAE J1616

standards for fuel composition and

quality.

The CNG system in your vehicle,

including the tank and hoses, has

been designed to hold gas at this

pressure. It has also been tested for

safety. You should never smell gas

or hear a hissing sound unless you

are refueling. If you smell gas or

hear a hissing sound at any other

time, you need to shut down the

CNG system. Follow the instructions

on page .12

Compressed Natural Gas (CNG)

Fuel

Before Driving

Compressed natural gas is

flammable and highly explosive.

You could be killed or seriously

injured if leaking natural gas is

ignited.

If you suspect a leak, have your

vehicle immediately inspected

and repaired by an authorized

Honda Civic GX dealer.

Main Menu

Your vehicle has an identifying

‘‘CNG’’ label attached next to the

rear license plate. Do not remove

this label. This label is necessary for

insuring your vehicle. Driving

without this label may violate the

laws or regulations in some states.

There are two methods of refueling,

fast filling or slow filling.

Fast filling is normally used in fuel

stations for natural gas vehicles. It

takes about 3 to 5 minutes to fill up

the fuel tank.

When refueling, you should use a

fuel fill nozzle that complies with

ANSI/AGA NGV-1-1994 standards.

Nozzles are designed according to

their maximum fill pressure: P24 for

2,400 psi (pounds per square inch),

P30 for 3,000 psi, and P36 for 3,600

psi.

Slow filling is done with a vehicle

refueling appliance. Refueling takes

about 1 hour per gasoline gallon

equivalent.

Always observe all safety

recommendations and operating

instructions on the refueling

equipment. During a fast fill, the natural gas is

warmed by the refueling process.

This causes the pressure in the tank

to rise and reduces the amount of

fuel you can put in.

Your vehicle’s maximum fill pressure

is 3,600 psi (24,800 kPa), so you

should refuel with a P36 nozzle.

Using a P30 nozzle will fill the tank

to the second (3,000 psi) fill mark on

the fuel gauge. Using a P24 nozzle

will not fill the tank completely.

A manual shutoff valve is located

underneath the vehicle, near the rear

tire on the driver’s side. We

recommend that you locate this

valve so you can find it quickly.

Fuel system maintenance and repair

should be done only by an authorized

Honda Civic GX dealer.

To turn off the valve, turn the lever

one-quarter turn clockwise. Turn it

counterclockwise to turn the valve

back on.

Turn off the valve if you ever suspect

a fuel leak or are involved in an

accident.

The in-tank fuel shutoff valve is

controlled by the ignition switch.

When the ignition switch is in the

LOCK (0) or ACCESSORY (I)

position, the valve is closed, shutting

off fuel flow to the engine. It opens

when the ignition switch is turned to

the ON (II) position. This is similar

to how an electric fuel pump works

in a gasoline-powered vehicle.

Tampering with, or improperly

maintaining the high-pressure

fuel system can cause a

dangerous condition in which

you can be seriously hurt or

killed.

Never attempt to modify the fuel

system, and always have fuel

system maintenance performed

by an authorized Honda Civic

GX dealer, or a qualified NGV

technician.

Main Menu

The maximum load for your vehicle

is 850 lbs. This figure includes the

total weight of all occupants, cargo,

and accessories.

Steps for determining correct load

limit:

Determine the combined weight

of the driver and any passengers.

Subtract the combined weight of

the driver and passengers from

850 lbs.

The resulting figure equals the

available amount of cargo and

luggage you can carry.

For example, if the maximum load

is 850 lbs and there are five 150 lb.

occupants in your vehicle, the

amount of available cargo and

luggage you can carry is 100 lbs.

(850 750 (5 150) = 100 lbs.)

The fuel tank is located in the trunk,

with a partition between the fuel

tank and the cargo space.

When you store small items in the

trunk, secure them so they will not

shift while you are driving. Loose

items can fly over the partition and

damage the fuel tank and fuel

system components.

Do not carry large, heavy, or pointed

objects in the trunk. They may

damage the fuel tank.

Determine the combined weight

of luggage and cargo in the vehicle.

That weight must not exceed the

available cargo and luggage load

capacity in step 3.

Carrying Cargo

Before Driving

Overloading or improper

loading can affect handling and

stability and cause a crash in

which you can be hurt or killed.

Follow all load limits and other

loading guidelines in this

manual.

Main Menu

Apply the parking brake.

In cold weather, turn off all

electrical accessories to reduce

the drain on the battery.

Make sure the shift lever is in

Park. Press on the brake pedal.

If the engine does not start within

15 seconds, or starts but stalls

right away, repeat step 5 with the

accelerator pedal pressed half-way

down. If the engine starts, release

pressure on the accelerator pedal

so the engine does not race.

Without touching the accelerator

pedal, turn the ignition switch to

the ON (II) position. You may hear

a click from the in-tank fuel

shutoff valve.

Make sure the malfunction

indicator lamp goes out before you

turn the ignition switch to the

START (III) position.

Turn the ignition switch to the

START (III) position. Do not hold

the switch in the START (III)

position for more than 15 seconds

at a time. If the engine does not

start right away, pause for at least

10 seconds before trying again.

If the engine still does not start,

press the accelerator pedal all the

way down and hold it there while

starting. As before, keep the

ignition switch in the START (III)

position for no more than 15

seconds. Return to step 6 if the

engine does not start. If it starts,

lift your foot off the accelerator

pedal so the engine does not race.

harder to start or may not start. In

is case, use the starting

procedure for cold weather at high

altitude described next.

Main Menu

If the engine fails to start in step 3,

push the accelerator pedal to the

floor and hold it there while you

try to start the engine for no more

than 15 seconds. If the engine

does not start, return to step 3.

An engine is harder to start in cold

weather. The thinner air found at

high altitude above 5,000 feet (1,600

meters) adds to the problem.

Use the following procedure:

Turn off all electrical accessories

to reduce the drain on the battery.

Make sure the malfunction

indicator lamp goes out before you

turn the ignition switch to the

START (III) position.

Push the accelerator pedal half-

way to the floor and hold it there

while starting the engine. Do not

hold the ignition switch in the

START (III) position for more

than 15 seconds. When the engine

starts, release the accelerator

pedal gradually as the engine

speeds up and smooths out.
